"One would think, as an enterprising indie developer, I’d jump straight on top of the hype train, shoot out another release, and begin dreaming up monetisation opportunities." My (now) 12 year old and me are working on a little game for a while. It started as a purely educational project, but I think it turned out good enough to be published. I don't want to commercialize it for multiple reasons, but I'm curious how this will go on the App Store. There are few truly and completely free apps so this is kind of uncharted territory. Since Apple does not earn anything from free apps, I can imagine they are not very keen on having them in the store. I am very curious to hear what experiences others had with publishing free apps. Was it hard to get them approved? Were they pulled from the store?
